Firefox Community Forum

Hello,

I’m experiencing an issue where I cannot use ChatGPT-5 in Firefox. When I log in and try to select or use GPT-5, nothing loads or functions properly. Other models like GPT-3.5 work normally, but GPT-5 does not respond.

I’ve already tried refreshing the page, clearing cache and cookies, and even disabling extensions — but the problem persists. Could this be a compatibility issue with Firefox? Any advice or support would be appreciated.

Thank you in advance for your help!

Yahoo Finance stock charts are not loading. Never encountered this problem before this week. A GeekSquad tech support person was not able to fix the problem and recommended I contact Firefox. Edge and Chrome load Yahoo Finance stock quote sites just fine; I'm only having trouble with Firefox. Any ideas on how to fix? Thanks! Carol

Every couple of days I am unable to access my email accounts, facebook and most web pages.

The only way I can access them is to refresh Firefox after which all work OK.

Really like firefox but am getting fed up of having to refresh it constantly any advise you could give would be very much appreciated.

Hi

I need to block some sites through the OS Hosts file, Other browsers ( Edge, Chrome, .. ) are honoring the HOSTS file rules but Firefox bypassing them !! , I disabled the DNSOverHTTPS and all other available suggestion and options but still not honoring the hosts file !

as you can see in the attached file, the Firefox DNS Section is now blank ! but still doesn't follow the OS host file

I even made a custom policy file but still doesn't work, these are the things I disabled but still not working :

{

 "policies": {
   "DNSOverHTTPS": {
     "Enabled": false,
     "Locked": true
   },
   "Preferences": {
     "network.trr.mode": {
       "Value": 5,
       "Status": "locked"
     },
     "network.dns.native_https_query": {
       "Value": false,
       "Status": "locked"
     },
     "network.trr.uri": {
       "Value": "",
       "Status": "locked"
     },
     "network.trr.bootstrapAddress": {
       "Value": "",
       "Status": "locked"
     },
     "network.trr.exclude-etc-hosts": {
       "Value": true,
       "Status": "locked"
     },
     "network.dnsCacheEntries": {
       "Value": 0,
       "Status": "locked"
     },
     "network.dns.disableIPv6": {
       "Value": true,
       "Status": "locked"
     },
     "browser.fixup.dns_first_for_single_words": {
       "Value": true,
       "Status": "locked"
     },
     "keyword.enabled": {
       "Value": false,
       "Status": "locked"
     }
   }
 }

}

When I want to login with my Firefox account it asks me for a code as 2 factor but I can't remember that I ever signed up for 2 -factor . I have 2 apps fro 2 factor: google and Microsoft but neither has Mozilla identification in it. I would like to sign up for 2 factor but it looks like someone already did that for me. What now?

I've gone through the various troubleshooting options over the last month or so and Firefox is still crashing constantly for me, even in Troubleshooting mode. The tabs crash when I'm using a Google Doc, YouTube, Discord, doesn't matter the site; I've submitted about 20 crash reports this morning alone and failed to submit several more:

Any help on this would be greatly appreciated!

firefox used to have good history now it's only 7 days? i need to see more than 7 days, all of it being available is ideal. what prompted this - although i've been irked by it before - is needing to know how i got to a website, what was the search and/or tab spelunking that got me there? it's really important to know this. relying solely on google search (if that'll yield part of the trail) seems contrary to firefox ethos.

Hello Mozilla Support Team,

I am writing to report a problem with the Mozilla Firefox browser. After the latest update, the browser appears to no longer decompress content that is compressed using the zstd (Zstandard) algorithm.

Previously, I could view web pages or resources compressed with zstd without issue, but now they fail to display correctly (or give errors). I have tested this on multiple websites and different systems, which suggests the change is not specific to one site or machine.

Could you please clarify the following:

Has support for zstd‐compressed content been removed or disabled in the recent Firefox version?

If so, are there plans to restore this support in a future release?

Is there a workaround or configuration setting that allows enabling zstd decompression in the meantime?

Thank you for your attention to this matter. I appreciate your help in ensuring this functionality is restored or clarified.

Best regards, Oleh Boiko Windiws 10, FF 144.0.2
